Hi, Jed here.
I like to build things.

Challenge

Building a zero-intervention trading system that manages real capital across three float tiers, with robust risk controls, 4x PDT margin utilization, and reliable EOD liquidation, all on a cost-efficient serverless infrastructure.

Solution

Go trading engine on ECS Fargate with EventBridge scheduling (~81% cost reduction vs always-on), a 14-step risk approval pipeline, SQS FIFO for per-symbol ordering, weekly walk-forward ML retraining with SHAP pruning and KS drift detection, and a real-time Svelte dashboard via WebSocket push.

Challenge

Traditional watermarks (visible overlays, LSB pixel-flipping) are trivially defeated by cropping, JPEG re-compression, or simply screenshotting the content, creating a new file with entirely different pixel values and potential geometric distortion.

Solution

Embeds AES-256-GCM encrypted payloads into mid-frequency DCT coefficients across 8x8 blocks, paired with an FFT-based pilot signal for geometric recovery. Video uses A/B adaptive streaming, dual-encoded segments form a per-user binary "DNA" sequence via manifest orchestration, eliminating per-user transcoding at scale.

Challenge

Design systems usually couple visual identity to specific framework code, forcing teams to rewrite their entire component library if they want to change their look or switch from React to Svelte. Additionally, preventing CSS leakage in complex enterprise apps is difficult without breaking customization capabilities.

Solution

Built a 'Design System Bridge' using Lit-based Web Components that leverage Shadow DOM for perfect encapsulation. The system features a library of 32 components across 6 categories, 12 pre-built themes, and a double-fallback token pattern. It includes auto-generated framework wrappers for React, Angular, Svelte, and Astro, ensuring a 'write once, use everywhere' workflow.
